Phusion Reaction

08-21-2019, 08:17 AM

My lab is working on a simple library prep and are running into an issue with our amplification PCR, our samples do not successfully amplify. After preforming the reaction (using 2X Phusion HF Polymerase, water, and our primers) for 12 cycles, the samples very low concentrations according to our qubit. In addition, when run on a gel we see nothing (including no primer dimers).

However when we use this product and run a standard QC PCR, the DNA amplifies successfully and can be seen on a gel.

For trouble shooting we have tried running the reaction with KAPA HiFi HotStrt ReadyMix and running the reaction for both fewer cycles (in case it was being overloaded) and for a greater number of cycles.

Has anyone run into this problem before or have other suggestions for trouble shooting?

Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems

by SEQadmin2

Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

Cancer Drug Resistance: The Lingering Barrier to Rising Survival

by SEQadmin2

Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

There is no single reason why many patients don’t respond to treatment as expected. Cancer is...

Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing

by GATTACAT

Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
